Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Ensure the vehicle is on a flat surface and engage the parking brake.

2. Inspect and Replace Air Filter

Locate the air filter housing.
Remove the screws or clips securing the housing.
Take out the old air filter and clean the housing if necessary.
Install the new air filter, ensuring it is seated properly.
Reassemble the housing and secure it with screws or clips.

3. Clean the Throttle Body

Remove the intake duct connecting to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Ensure that the throttle plate can move freely after cleaning.
Reconnect the intake duct securely.

4. Replace Spark Plugs

Locate the ignition coils on top of the spark plugs.
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils using a socket wrench.
Use a spark plug socket to remove the old spark plugs.
Install new spark plugs, tightening them to the specified torque (typically around 13 lb-ft).
Reinstall the ignition coils and reconnect the electrical connectors.

5. Check and Replace Transmission Fluid (if necessary)

Locate the transmission dipstick and check the fluid level; add fluid if low.
If the fluid is dirty, remove the transmission pan using a socket set and drain old fluid.
Replace the transmission filter if applicable and refit the pan with a new gasket.
Refill the transmission with the recommended type and amount of fluid.
